BACKGROUND ART

Early massage devices were typically designed as therapeutic chairs, mattresses, and the like wherein one or more vibrating members were embedded therein for imparting vibratory energy to a user. Typically, the vibrating members were placed under a frame, box spring or the like, such that when oscillated, vibratory energy was transmitted through the mattress or cushion structure indirectly. Such movements were typically localized and unappealing. See, for example, U.S. Pat. Nos. 2,924,216, 3,885,554, 5,007,410, 5,050,587, 4,354,067, 4,256,116, 4,005,703, 4,157,088, 4,544,867, 3,678,923 and 4,779,615.

There have been attempts to overcome the aforementioned difficulties by providing vibrating units arranged in selective groups or arrays, the control of which provides the illusion of a rolling or travelling motion to the user. These designs, however, typically incorporate complex electromechanical structures and/or electronics. See, for example, U.S. Pat. Nos. 3,446,204, Re. 31,603, 5,192,304, 5,437,608 and U.K. Patent No. GB 2,256,147A.

One method for providing an illusion of a rolling or traveling motion to the user is disclosed in U.S. Pat. No. 5,437,608 which uses a counter to sequentially actuate each zone or group of vibrating units. This approach, however, is inflexible in that the sequence of operation is fixed. Furthermore, only one group or zone may be actuated at any one time.

Consequently, a need has developed for an improved massage apparatus having a plurality of vibrators coupled to a cushion structure which incorporates a simple hand-held controller for controlling both the rate and duration of energization of each of a plurality of vibrators as well as the intensity of vibratory energy imparted thereby.

SUMMARY OF THE INVENTION

It is a principal object of the present invention to provide a massage apparatus having an improved controller with simplified electronics for controlling the rate and duration of energization and the intensity of vibratory energy, respectively, imparted by each of a plurality of vibrators embedded in a cushion structure.

It is a further object of the present invention to provide massage apparatus of the type referenced above wherein the improved controller incorporates a power control unit operative to generate a plurality of power control signals at timed intervals variable by the user and a variable intensity control unit operative to generate pulse width modulated signals to produce the intensity selected by the user.

A still further object of the present invention is to provide massage apparatus utilizing a microcontroller which allows actuation of one or more vibratory zones based on selection by the user.

Yet another object of the present invention is to provide massage apparatus which utilizes a microcontroller to provide flexibility of design and improved authority of control over a plurality of vibratory zones including the ability to sequentially actuate two or more of the vibratory zones.

In carrying out the above stated objects, there is provided a massage apparatus of the type having a plurality of vibrators coupled to a cushion for imparting vibratory energy thereto and to a user. The invention includes a microcontroller having multiplexed inputs and outputs. The microcontroller generates pulse width modulated signals to generate an effective DC signal for controlling vibration intensity by controlling rotational speed of the vibrator motors. The massage apparatus generates a reminder signal which actuates at least one of the vibrators after a predetermined time interval when the apparatus is turned on but none of the vibratory zones are selected by the user.

In a preferred embodiment, the cushion structure is elongated, foldable and comprised of resilient material. The vibrators coupled thereto are DC motors with eccentric cams with housings carried in the cushion in a fixed, spaced-apart relationship constituting a multiplicity of massage zones across the length of the cushion. The controller is located external to the cushion structure and is adapted to be hand-held.

These and other objects, features and advantages of the present invention are more readily apparent when taken in conjunction with the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

With reference to FIG. 1 of the drawings, there is shown a schematic diagram of the massage apparatus of the present invention designated generally by reference numeral 10. Massage apparatus 10 is shown as an elongated and foldable pad comprised of a resilient material such as polyurethane, or the like. Apparatus 10 may, of course, be used in many forms such as an upholstered item of furniture, an automobile seat, a chair, or may be a separate cushion, mattress or a pad as shown.

In the schematic of FIG. 1, massage apparatus 10 includes an elongated cushion structure such as pad 12 which may be laid flat or folded as shown for placement on a chair, automobile seat, etc. Apparatus 10 includes a head portion 14, a mid or torso portion 16, and a bottom or seat portion 18 to correspond to head, torso and seat portion, respectively, of a user.

As shown, apparatus 10 includes massage motors or other vibrators in each of the portions. In a preferred embodiment, the torso portion 16 and the seat portion 18 each include two vibrators. Of course, a greater or lesser number of vibrators may be utilized according to the teachings of the present invention.

As also shown in FIG. 1, massage apparatus 10 includes retaining straps such as straps 20, and a positioning web 22 for securing the massage apparatus to a chair, automobile seat, or the like. The massage apparatus 10 also includes a hand held controller 24 which is preferably connected to the seat portion 18 and also adapted for connection to a power source via cord 26. As explained in greater detail herein, the power source is preferably a 12 volt DC source to facilitate operation in an automobile. However, an AC adaptor may also be provided to supply the appropriate power. Hand held control 24 includes a number of indicator lights, such as LED 28, and a number of switches or push buttons 30.

Referring now to FIG. 2, a partial cross-section of the massage apparatus 10 illustrated in FIG. 1 is shown. A durable, removable cover 20 surrounds a foam core 22 which is preferably accessible via a zipper. Foam core 22 includes an aperture for each vibrator 23 which is covered by a small piece of foam 24 secured to foam 22 via adhesive 36. Vibrator 23 is also secured to foam 22 via adhesive 36'.

With continuing reference to FIG. 2, in a preferred embodiment, vibrator 23 includes a housing having a base plate 32 and a shroud 34 which surround a DC motor 26 supported by tab 28. Preferably, tab 28 is integral to base plate 32 and is bent perpendicular thereto to support motor 26. DC motor 26 includes a cam 30 which is eccentrically mounted to produce vibration when the motor turns. The user will experience various vibrational intensities depending on the speed of rotation of DC motor 26 and cam 30. Such vibrators are well established in the art. Of course, various other vibrating arrangements could be utilized without departing from the spirit or scope of the present invention.

Referring now to FIG. 3, a block diagram illustrating control of a massage apparatus according to the present invention is shown. In a preferred embodiment, Control Process 300 is implemented within a microcontroller, such as the FLSS/1299 which is an 8 bit microcontroller implemented in a fully static CMOS design using low power, high speed CMOS technology. Control Process 300 communicates with LED decode block 302 to control 12 LEDs, represented by block 304. However, the control is multiplexed such that only seven data lines are needed as illustrated and described in greater detail with reference to FIG. 4. Control Process 300 also communicates with input key decode block 303 which multiplexes eight switches, represented by block 306. This allows eight inputs to be monitored using only six input lines.

With continuing reference to FIG. 3, control process communicates with a timer/counter 308, an auto sequencer 310, and a prescaler 312. Timer/counter 308 keeps track of a warning interval, preferably about 15 minutes, to remind the user that power is on when none of the motors has been selected by the user. Auto sequencer 310 controls sequencing through selected vibrator motors when the automatic sequencing mode is selected by the user. Prescaler 312 is used to control the speed of the auto sequence block 310 in addition to the intensity of the vibrator motors. The prescaler provides selectable divisors which are applied to the system clock signal to generate a lower frequency periodic signal.Intensity is controlled using pulse width modulated signals as illustrated and described in detail with reference to FIGS. 5a-5c. Timer/counter 308, auto sequencer 310 and prescaler 312 communicate with motor on/off control 314 to control motors M1-M5, represented by block 316. In a preferred embodiment, the user may select which of the five portions or zones of the massage apparatus to be actuated, whether to continuously actuate the selected zones or automatically sequence through them, the strength or intensity of vibration, and the speed of cycling.

Referring now to FIG. 4, a circuit schematic is shown illustrating the control of a massage apparatus according to the present invention. Preferably, all of the components illustrated in FIG. 4 reside on a printed circuit board disposed within hand controller 24. Control circuit 200 includes a DC motor driver circuit 202 which converts signals received from microcontroller 206 into acceptable signals to drive the DC motors 26 disposed within massage apparatus 10. An oscillator circuit 204 is connected to microcontroller 206 and includes components such as resistor R14 and capacitor C3 to produce an input oscillation frequency of about 2 MHz. An indicator output circuit 208 is used to provide an indication to the user of the current operating mode. Control circuit 200 also includes a power conditioning circuit 210 which filters and regulates the power input to microcontroller 206. Preferably, the input voltage, V_dd is regulated at about 5.1 volts by zener diode D21.

With continuing reference to FIG. 4, control circuit 200 includes a fuse and a power jack connector, indicated generally by reference numeral 212. A power switch 214 is provided, which is preferably a three position sliding switch having positions for off, on, and heat. In a preferred embodiment, heat is provided to all zones of massage apparatus 10 when sliding switch SW1 is positioned to select heat. LED 215 provides an indication to the user that the massage apparatus 10 is on and heat has been selected. Circuit 202 includes a connector terminal 220 so that hand held controller 24 may be disconnected from the cushion mat. Circuit 202 includes a number of diodes 222 connected to corresponding transistors 224. The transistors receive signals from the microcontroller 206 and provide a ground signal for their corresponding motors which are connected to pins 2-6 of terminal 220. Pin 1 of terminal 220 provides power to all five of the motor vibrators.

Circuit 208 includes twelve indicator lights or LEDs which are controlled by microcontroller 206. As illustrated, the indicators 248 are multiplexed using three common lines 240, 242, and 246 and four individual signal lines, ROW0-ROW3. These individual lines are also connected to switches S1-S8 which have corresponding common lines, such as common line 252.

FIGS. 5a-5c illustrate representative signals produced to control the vibrating motors of massage apparatus 10. FIG. 5a represents a continuous actuation signal for three different levels of vibration. The high signal, indicated by H is a pulse train having a duty cycle of approximately 97%. The pulse train is a series of substantially rectangular pulses which are sent to one or more of the vibrator motors as selected by the user. As illustrated, regardless of whether the user selects high, medium, or low vibration intensity, the rectangular pulses go from about 0 volts to the supply voltage which is about 12 volts in a preferred embodiment. By varying the duty cycle of the pulse train, the effective DC voltage seen by the various vibrator motors changes as indicated by the broken lines which alters the average motor speed accordingly. The pulse width modulated signal is produced by two timers within the microcontroller which represent the time period that the pulse is high, and the time period that the pulse is low, respectively.

FIG. 5b illustrates representative signals during the automatic sequencing mode of the present invention. Although, only three motor signals are illustrated, the concept is easily extendable to five or more motors. As illustrated, the motors are sequentially energized in an alternating pattern such that only one motor is energized during a particular time interval. The time interval is controlled by the cycling speed selected by the user. In a preferred embodiment, three cycling speeds are available. The cycling speed is independent of the vibration intensity which is controlled by the duty cycle, or pulse width of the signals. Similarly, the present invention provides for alternating sequential operation among selected motors. For example, the first, fourth and fifth motors may be selected by the user. During auto sequencing, motor 1 is actuated for a first time period, followed by motor 4, motor 5, motor 4, motor 1, etc.

FIG. 5c illustrates representative signals for auto sequencing using a faster sequencing speed (shorter time interval). The auto sequencing pattern continues until deselected by the user via a cycle push button. As illustrated in FIGS. 5a-5c, the rectangular pulse trains always swing from about 0 volts to the level of the power supply regardless of the vibration intensity or the sequencing speed.

Referring now to FIGS. 6-11, flow charts illustrating operation of the control program within microcontroller 206 are shown. As indicated by block 50 of FIG. 6, when power is applied to the system, a reset program is executed. The reset program is illustrated in FIG. 7. Block 60 of FIG. 7 initializes the data ports of the microcontroller (Port A and Port B). These data ports are configurable as inputs or outputs depending on the content of the corresponding control registers. Preferably, pins PA0-PA3 and PB0-PB5 are configured as outputs while pins PA4-PA7 are configured as inputs. As such, the present invention uses multiplexing techniques to control seventeen outputs (twelve LEDs and five vibrator motors) via eight selector switches (momentary contact push buttons) using only ten outputs and four inputs of the microcontroller.

Block 62 of FIG. 7 sets the timer/counter register which is used to periodically generate an interrupt. Blocks 64, 66, and 68 represent initialization of the LEDs, vibrators, and pulse width memory locations, respectively. These blocks essentially clear the memory locations to eliminate the possibility of any spurious operation. Block 70 illuminates the default LEDs. For example, when power is applied to the system, the "low" cycle speed LED is illuminated in addition to the "low" vibration intensity LED.

Block 72 initializes the fifteen minute timer using a subroutine call. This timer is used to generate a user warning or reminder indicating that the system is on but that no vibrator motors have been selected. In a preferred embodiment, this reminder actuates the vibrator motor located at the lower torso for approximately ten seconds with a "medium" intensity level.

Blocks 74, 76, and 78 perform additional initialization functions. Block 80 calls the key scan subroutine which is responsible for decoding the push button inputs. Block 82 calls the LED processing subroutine which is responsible for decoding the LED outputs to illuminate the appropriate LEDs.

Block 84 determines whether any of the push buttons have been depressed while block 86 calls the key processing subroutine to take appropriate action based on the key or keys which have been depressed. Block 88 is an infinite loop which essentially ends execution of the reset routine until an interrupt is generated.

FIG. 8 illustrates a simple initialization routine which loads appropriate values into three different timers as indicated by blocks 100, 102, and 104. These timers control the interval between the warning or reminder actuation of the torso vibrator motor, as well as the duration and intensity of the reminder signal. For example, in a preferred embodiment, block 100 loads a first timer with a value corresponding to a timer of about fifteen minutes. Block 102 loads a second timer with a value corresponding to the duration of the reminder signal which is about ten seconds. Block 104 loads a third timer with a value representing the vibration intensity, i.e. the pulse width, which corresponds to a medium intensity or a duty cycle of about 78%.

Referring now to FIG. 9, a key scan routine is illustrated. Block 110 determines whether a push button has been depressed. Block 112 decodes the signal to determine which of the push buttons has been depressed based on the two signal lines corresponding to one of ROWS 0-3 and common lines COM0 and COM1. Block 114 determines whether the push button is being continuously held down in which case the routine is exited and control is returned to the calling routine. Block 116 determines whether there has been a repeat key press by maintaining a memory location which may be incremented to advance the system to the subsequent state. For example, when power is applied to the system, the vibration intensity defaults to "low". The first press of the intensity push button advances the intensity to the "medium" state. Subsequent depressions of the intensity push button will cycle through the available states from "low" to "medium" to "high" and then back to "low". Cycle speed selection for auto sequencing mode is performed in a similar fashion. The incrementing and resetting function to cycle through the appropriate states is represented by block 118 of FIG. 9.

Referring now to FIG. 10, the timer/counter interrupt subroutine is illustrated. This controls the functioning of the warning or reminder signal as described above. At block 130, the current timer is loaded. Block 132 determines when the timer interval has expired in which case block 136 calls another interrupt service routine. Otherwise, block 134 decrements the count and control is returned to the calling routine.

Referring now to FIG. 11, a pulse width modulation routine is illustrated. Block 140 represents various "housekeeping" tasks which may be required to save the contents of registers which are used to produce the PWM signal. Block 142 represents the dwell time for the low or off state of the vibrator motor. Block 144 represents the various register moves to accomplish the transition from the low to the high state. Similarly, block 146 represents the dwell time for the high or on state of the vibrator motor. This process is repeatedly executed to produce a train of rectangular pulses.
